[FastISel][AArch64] Fix and extend the tbz/tbnz pattern matching.

The pattern matching failed to recognize all instances of "-1", because when
comparing against "-1" we didn't use an APInt of the same bitwidth.

This commit fixes this and also adds inverse versions of the conditon to catch
more cases.
